The Nikon Keymission 360 gets reviewed by DigitalRev!
I love watching DigitalRev's irreverent reviews. Here's their review of the Keymission, including testing it out with a DJI Phantom 4 drone! The review is not by Kai but I thought Lok did a great job in the review (and with flying the drone!).
I agree with Lok's review, except that for me, the inability to stitch well at close distances is not a defect - it's just a matter of physics / optics. If you haven't seen it yet, here's my review of the Keymission 360.
